This book aims to provide academic and industrial applications advancing the critical role of circular economy principles in the sustainability of various resources. The latest research and practice in resource sustainability are shared, discussed, and promoted. The core competency of this book revolves around providing recent advances in sustainable consumption and production implementations, developed tools for environmental and sustainability assessment, technological advancements in resource and waste management/treatment, and advances in waste reduction, reuse, recycling, and recovery. Resources are defined broadly to include (1) physical resources: metals, non-metallic minerals, energy, and water (2) biological resources: food, forestry, land, ecological systems, etc., and (3) "misplaced" resources: air emissions, water pollutants, and solid waste.
